DETAILED DESCRIPTION OF THE INVENTION

The following is specific embodiments of this disclosure and furtherdescribes the technical solution of this disclosure with reference tothe drawings, but this disclosure is not limited to these embodiments.

As shown in FIGS. 1 to 4 , a cup lid assembly includes a cup lid body100, a flip cover 200 and a button 400, wherein the cup lid body 100 canbe detachably connected with a cup body, and a catch 110 is arranged onan upper end surface of the cup lid body 100; the flip cover 200 isconnected to the cup lid body 100 in a flipable manner, so that the cuplid can be opened or closed. Specifically, the cup lid can be flipped toa closed position or an open position.

The button 400 is configured for unlocking. The button 400 is connectedwith the flip cover 200 and capable of translating on the flip cover200, and the button 400 can move to a locking position or an unlockingposition. The button 400 is provided with a hook 410, and the hook 410and the catch 110 can be locked together.

It should be noted that as mentioned above, the button 400 is connectedwith the flip cover 200 and can translate on the flip cover 200, whichmeans that the button 400 can only translate relative to the flip cover200, so the button 400 is equivalent to a part of the flip cover 200.When the button 400 and the cup lid body 100 are locked together, it isequivalent to that the flip cover 200 and the cup lid body 100 arelocked together, so that the flip cover 200 cannot be rotated.

The button 400 is translationally arranged on an upper end surface ofthe flip cover 200, the flip cover 200 is provided with an avoidancegroove 220, the avoidance groove 220 is structured as a through hole,and the hook 410 and the catch 110 are both located in the avoidancegroove 220, so that the hook 410 and the catch 110 can pass through theflip cap 200 and can be connected to each other or separated from eachother. Moreover, the arrangement of the avoidance groove 220 can alsoprevent the hook 410 from interfering with the flip cover 200 during thetranslation of the button 400.

The flip cover 200 is provided with a translation groove 230, and thebutton 400 is arranged in the translation groove 230 and can move alongthe translation groove 230. Since the button 400 can only translatealong the translation groove 230, during the closing process of the flipcover 200, the hook 410 slides along a horizontal direction (i.e., alongan arrangement direction of the translation groove 230) and is locked inthe catch 110, and the hook 410 and the catch 110 can only be unlockedthrough the translation of the button 400. In this way, the flip cover200 can be well limited from flipping up. Even though the flip cover 200is subjected to a force to make it flip up, the button 400 cannot betranslated, which ensures the reliable locking of the button 400 verywell.

In an actual structure, limiting grooves 270 are formed in two sides ofthe translation groove 230, limiting blocks 430 are arranged on twosides of the button 400, and the limiting blocks 430 are arranged in thelimiting grooves 270, so that the sliding stroke of the button 400 canbe limited, and the button 400 and the flip cover 200 can be fixedtogether.

As shown in FIGS. 1 and 2 , the flip cover 200 is provided with anelastic member 300. The elastic member 300 can be configured as a springor elastic silica gel part or other elastic components. The elasticmember 300 is connected with the button 400. A cavity is formed betweenthe flip cover 200 and the button 400. The elastic member 300 can beflatly placed in the cavity, and two ends of the elastic member 300respectively push against and are in connection with the button 400 andthe flip cover 200.

Specifically, the elastic element 300 keeps the button 400 at thelocking position, and when the button 400 is at the locking position,the hook 410 is connected with the catch 110 and limits the flip cover200 from being opened (in this case, the flip cover 200 is at the closedposition). When the button 400 is moved to the unlocking position, thehook 410 is separated from the catch 110.

Therefore, the elastic member 300 has at least two functions: 1. whenthe flip cover 200 is closed, the elastic member 300 pushes the hook 410to be locked with the catch 110, thus ensuring the locking reliabilityof the flip cover 200; 2. when the button 400 moves toward the unlockingposition, the elastic member 300 is compressed and can drive the button400 to return.

Therefore, the flip cover 200 of the cup lid can be opened in a slidingunlocking manner. When the button 400 is at the locking position, theflip cover 200 is kept closed, and when the button 400 is translated tothe unlocking position, the flip cover 200 can be opened, so theoperation is convenient. When closed, the flip cover 200 is locked bythe hook 410 and the catch 110, thereby achieving a good locking effectand avoiding water leakage.

As shown in FIGS. 1,2 and 4 , on the basis of the above embodiment, thecup lid body 100 is further provided with a drinking opening 130, andwhen the flip cover 200 is closed, the flip cover 200 covers thedrinking opening 130 and the hook 410 is connected with the catch 110.Preferably, the flip cover is provided with a sealing block, and whenthe flip cover 200 is closed, the drinking opening 130 is blocked by thesealing block 210. In this way, it can be ensured that the sealing block210 seals the drinking opening 130 when the flip cover 200 is closed,thereby improving the sealing performance of the drinking opening 130and avoiding water leakage.

The flip cover 200 is provided with a rotating shaft 250 and hinged withthe cup lid body 100 through the rotating shaft 250. A torsion spring260 is fitted over the rotating shaft 250, one end of the torsion spring260 is connected with the cup lid body 100, and the other end of thetorsion spring 260 is connected with the flip cover 200. When the hook410 is separated from the catch 110, the torsion spring 260 drives theflip cover 200 to open.

Preferably, an elastic force for opening is applied to the flip cover200 through the torsion spring 260. When the flip cover 200 is closed,the torsion spring 260 cannot drive the flip cover 200 to open becausethe hook 410 is engaged with the catch 110, and once the hook 410 isseparated from the catch 110, the torsion spring 260 can automaticallyopen the flip cover 200.

As shown in FIGS. 1 and 2 , the hook 410 is provided with a firstdriving surface 420, and the catch 110 is provided with a second drivingsurface 120. When the flip cover 200 is flipped toward the cup lid body100, the first driving surface is matched with the second drivingsurface and the button 400 is then driven to move, so that the hook 410is connected with the catch 110.

It should be noted that, because the elastic member 300 can push thebutton 400 to the locking position, when the flip cover 200 is to beclosed again, there is a problem that the hook 410 interferes with thecatch 110, resulting in that the flip cover 200 cannot be closed. Toensure that the hook 410 is automatically engaged with the catch 110during the closing process of the flip cover 200, the first drivingsurface 420 and the second driving surface 120 are specially provided.

Preferably, the first driving surface 420 and the second driving surface120 can be configured as an inclined surface or a cambered surface. Inthe movement process of the flip cover 200 flipped toward the cup lidbody 100, firstly, the first driving surface 420 and the second drivingsurface 120 push against and are connected with each other, and then thebutton 400 is pushed by the hook 410 to move toward the unlockingposition for a short distance. In this way, the flip cover 200 can becompletely closed on the cup lid body 100, and in this case, the elasticmember 300 pushes the button 400 to return to the locking position, andthe hook 410 is connected to the catch 110.
